WHAT IS A SOUND OR A NOISE?The sound is composed by longitudinal mechanical waves, characterized by a pressure deviation (+∆pt compression phase, -∆pt rarefaction phase) from an equilibrium point. In case the sound transmits in the air, the equilibrium point is represented by air atmospheric pressure. Like every waves, the sound waves are defined by physical parameters such as frequency, speed, wave length, amplitude.

The acoustic pressure is the most distinctive parameter of a sound/noise, basically defining its volume. Unit measure of pressure is Pascal, but, since the sound pressure variation is very low, the standard measure scale is the Decibel logarithmic scale:

Lp = 20 * Log ( ) [dB]

Where P0 = 2 * 10^(-5) is the lowest limit (threshold of hearing).

The pressure level are commonly used to define, measure, and test all the products/systems related to acoustic insulation in buildings.The Logarithmic scale means that the doubling of noise power/source results in an increase of + 3 dB.One speaking person is about 60 dB of sound pressure, two speaking people correspond to 63 dB, not to 120 dB!

NOISE PROPAGATIONThe noise propagation can occur mainly in two ways:• Airborne propagation: the sound transmits through the air• Structure-borne propagation: the sound is connected to vibration of solid elements.

In terms of acoustic insulation, the first propagation mode is linked to airborne sound insulation, façade insulation and partly to service equipment acoustic insulation. The second is related mainly to impact sound insulation. The service equipment sound propagates in both modalities, therefore it is discussed in separated paragraph.

AIRBORNE SOUND

The airborne sound is transmitted through the air. Sound waves propagate firstly in the area/room where they are originated. Then, when the waves reach another surface and/or obstacle (i.e. separation wall), the sound energy is partly reflected and absorbed, and partly transmitted through separation elements. The aim of acoustic insulation system is to decrease as much as possible the transmitted part and, furthermore, avoid too much reflected noise. In building sector, the airborne sound is related to the following situations:

• External noise, such as façade insulation (external walls and roofs). The measurement parameter can be different country by country according to national regulation, but it is generally indicated with the descriptor Dnt,w, “weighted standardized level difference”. The higher is the value of the descriptor, the better the façade is acoustic insulated.

• Internal noise (between different rooms). In this case the most common descriptors are Dnt,w (the same as above); R’w (in-situ) and Rw (laboratory), “weighted sound reduction index”. The latter is commonly used to characterize products and systems in terms of sound insulation, with laboratory and in-situ tests. Also in this case, the descriptors value needs to be as high as possible for products and systems.

Part of the airborne sound is reflected in the same area where it is originated: this fraction is known as Reflected sound. It is commonly described as “echo or reverberation effect” in the field of room acoustic and it can be source of disturbance especially where good level of room acoustic is required (conference rooms, offices, theatres, etc.). In order to decrease the reflected sound, it is necessary to apply sound absorption materials over the surfaces hit by the sound waves. The most common descriptor for sound absoprtion is the α Sabine coefficient, while the quality descriptor of an entire room/space is given by reverberation time T. the two parameters are linked by inverse proportionality: the higher is the α Sabine coefficient of the materials, the lower is the reverberation time T and the better is the internal acoustic quality of the room.

STRUCTURE-BORNE/IMPACT SOUND

This kind of noise is typically generated by direct impact (i.e. falling objects) or structures vibration. It is known as Impact sound: the noise caused by steps, falling objects, etc. and propagated through floors and lateral structure in different rooms of buildings. The most common descriptor is L’n,w (in-situ) or Ln,r,w (

1) laboratory tests), which are weighted standardized sound pressure levels. As the descriptor is a “sound level”, it is recommendable to reduce it as much as possible. Detailed information are provided in the dedicated Trocellen brochures.

SERVICE EQUIPMENT SOUND

The service equipment in buildings generate both airborne and structure-borne sound, according to the system type and installation. The first kind of propagation comes from the equipment through air directly, while the second is propagated through structures vibration, and it is mainly generated by rigid connection of the equipment with building elements (walls, floors, etc.).

Among the several service equipment, waste water pipes can be the most disturbing: the technical standard EN 14366 defines a complete procedure to test and evaluate the result of insulation products application on waste water tubes.

1) For laboratory tests, it is usually reported the difference between sound pressure level ∆Lw

ISOLMASS 11

Under the APLOMB brand, TROCELLEN has been commercializing for many years a multi-layer product, with one or more sheets of lead, laminated with flexible insulating materials. Lead is not always readily accepted by installers and designers; which is why we have developed an alternative with a polyolefin heavy layer.
